BACKGROUND Field of the Invention

The present invention relates generally to the field of over-lock and release systems for rentable facilities. More particularly, the invention is a distributed management system for self-storage facilities that allow for vacant units to be secured with over-locks, and which allow the over-locks to be removed by customers without human or manual intervention from the self-storage facility.

Description of Related Art

Self-storage units are typically rented on a monthly basis. If a customer is delinquent, and does not pay their rent to the self-storage facility owner by an agreed-upon due date, the owner (i.e., landlord) has a right to prevent the customer from accessing the storage unit. Self-storage facility owners typically place an over-lock over the storage unit door, such as through a hasp that prevents opening of the door. The over-lock is utilized until the customer pays the delinquent past due balance on their account.

The process of placing, and removing over-locks, can be quite burdensome on a self-storage facility owner, especially with large facilities with hundreds of storage units, the majority of which may be rented to month-to-month customers. After an over-lock is placed on a storage unit, the over-lock must ultimately be removed once the customer account becomes non-delinquent. Removing over-locks is time-consuming and costly because it requires personnel from the self-storage facility to physically go to the storage unit and remove the over-lock.

In addition, the cost of conventional over-locks can be prohibitive. Many conventional over-locks are electronic and provide automated and remote locking/unlocking functions. Such over-locks oftentimes require significant capital improvements on the storage structures, as these over-locks must be installed behind the storage door on the interior of the space. Furthermore, these electronic locks inherently require constant power, and their continuous twenty-four hour operation increases power consumption costs for the self-storage facility.

Furthermore, as with any complex electronic device, electronic over-locks are subject to failure and malfunction, and can require costly repairs to be conducted by an electrician, if not ultimately requiring replacement.

Other conventional over-locks include standard combination locks. However, with a self-storage facility utilizing a limited number of standard combination over-locks, habitually delinquent customers eventually begin to recognize the unlock codes, and these over-locks become futile. The self-storage facility must then perpetually replace over-locks with unlock codes that have become known and compromised.

Another disadvantage of standard combination over-locks is the potential for delayed access to the customer. If the customer makes a payment and brings their account current when the self-storage management office is closed or when personnel are unavailable, such as on weekends, after-hours, or holidays, the customer must then wait until the office is open and there are personnel available to remove the over-lock. Thus, the customer cannot gain access to their storage unit and possessions immediately after making payment to bring their account current. The delay between such a payment and removal of the over-lock does not cater to tenants who may need immediate access to their storage unit.

Another challenge in managing self-storage facilities is securing vacant storage units when they are not being rented. If the vacant units are not properly secured, these units can be entered illegally and be used to store items for free by unauthorized persons, could be used to discard trash, and could be used for other illicit or illegal activities that could pose liability and safety issues for the self-storage facility and customers of the self-storage facility. Currently, vacant units must be secured using traditional locks. In the event a locked vacant unit is subsequently rented, a representative of the self-storage facility must manually visit the unit and remove the lock. Such a process is burdensome, manually intensive, and increases the time between a customer renting a unit, and actually being able to access the unit.

Thus, there is a need in the self-storage industry for a system that allows or disallows access to an over-locked storage unit, such as a vacant storage unit, without the need for an on-site attendant. Such a distributed over-lock system would allow for immediate access to an over-locked storage unit, would encourage delinquent customers to bring an account current in a timely fashion, and would reduce operational costs associated with conventional electronic and standard combination over-lock systems.

DETAILED DESCRIPTION

It should be understood that aspects of the invention are described herein with reference to the figures, which show illustrative embodiments. The illustrative embodiments herein are not necessarily intended to show all embodiments in accordance with the invention, but rather are used to describe a few illustrative embodiments. Thus, aspects of the invention are not intended to be construed narrowly in view of the illustrative embodiments. In addition, the present invention is an over-lock and release system. Although the system is described with respect to its application for self-storage facilities, it is understood that the system could be implemented in any setting where an over-lock system may be useful.

FIG. 1 is a network architecture diagram of a distributed encrypted combination over-lock and release system. In an embodiment, the system can be implemented within a self-storage environment. The system includes a self-storage facility 102 coupled to a management site 118 via a network 116. The management site 118 can be remote from the self-storage facility 102, and the management site 118 can serve multiple distributed self-storage facilities, such as in a central management site. The management site 118 can further be located overseas, such as in a foreign call center.

In an embodiment, the management site 118 includes computing hardware and software 119, consisting of a processing unit 120, a database 122, and a transceiver 124. The computing hardware and software 119 can include a server coupled to the network 116. In another embodiment, the processing unit 120 and database 122 can be cloud-based, and located on a server remote from the management site 118, such as on a server provided by Amazon Web Services® or the like.

In another embodiment, the management site 118 can be located within the local vicinity of the self-storage facility 102, such as on-site. The management site 118 can be a physical location with human personnel, such as a self-storage manager 108. In another embodiment, the management site 118 can be unmanned, and can include only the computing hardware and software 119. The network 116 may be any type of network suitable to allow interaction between devices, such as a mobile device 112 located at self-storage facility 102, and the computing hardware and software 119 at the management site 118. For example, the network 116 may be a wired network, a wireless network, or any combination thereof. Further, the network 116 may include a distributed computing network, an intranet, a local-area network (LAN) and/or a wide-area network (WAN), or any combination thereof. For example, the LAN may make use of WIFI in its many variations and the WAN may make use of broadband, cellular and/or satellite networks using technologies including, but not limited to, CDPD, CDMA, GSM, PDC, PHS, TDMA, FLEX, ReFLEX, iDEN, TETRA, DECT, DataTAC, Mobitex, EDGE and other 2G, 3G, 4G and LTE technologies. However, those of ordinary skill in the art will appreciate that the network 116 is not limited thereto.

The self-storage facility 102 can include a storage unit 104, which can be rented by a customer 106. As used herein, the term “customer” can include a renter, client, tenant, lessee, user, or an authorized agent. Although the invention will be described with respect to self-storage facilities, the invention can be implemented in any setting where an over-lock system may be useful, such as hotel rooms, apartment buildings, storage containers, short-term housing rentals, and lockers. In addition, the invention can be implemented within a controlled access system, such as for equipment rooms, vaults, hospitals, airports, government facilities, nuclear power facilities, water treatment facilities, weapon storage facilities, aircraft cockpits, and any other setting that requires restricted, selective, or monitored access.

In the event that customer 106 becomes delinquent in the payment of rent, the self-storage manager 108 can place an over-lock 110 on the storage unit 104. The over-lock 110 is a secondary lock that is used to prevent the customer 106 from accessing the storage unit 104 until the delinquent past due balance is paid by customer 106.

In a preferred embodiment, the over-lock 110 is a combination padlock that requires an unlock code to be manually entered in order to open the over-lock 110. In another embodiment, the over-lock 110 can be deadbolt, knob lock, or lever lock that includes a combination mechanism. The combination mechanism can include a tubular barrel, a rotary knob, pushpins, or a mechanical keypad. In another embodiment, the over-lock 110 can be an electronic lock that accepts a combination input via digital keys or a touchscreen. In an embodiment, the over-lock 110 is a lock with no electronic circuitry or electronic components, and the over-lock 110 is not capable of electronic communication with any remote or local systems.

In an embodiment, the over-lock 110 can include an identifier, such as a serial number, unique code, barcode, QR code, or other unique indicia. In an embodiment, the identifier is engraved onto the over-lock 110. In other embodiments, the identifier is affixed via a label to the over-lock 110, affixed to a tag that is attached to the over-lock 110, or otherwise imprinted, drawn, or engraved on the over-lock 110 or tag.

Upon payment of a delinquent past due balance by the customer 106, the management site 118 can enable the release of an unlock code for the over-lock 110. At this time, the customer 106 can use a mobile device 112, such as their mobile phone, to access a software application 114 created by the self-storage manager 108. The software application 114 can be a proprietary program created and/or owned by the self-storage facility 102, and which can be downloaded by the customer 106 from, for example, a website operated by the self-storage manager 108, the Apple iTunes App Store®, the Android App Store®, and the like.

The software application 114 can allow bi-directional communication between the mobile device 112 and the management site 118, self-storage manager 108, processor 120, database 122, and/or transceiver 124.

In yet another embodiment, the software application 114 is a website accessed via a Uniform Resource Locator (URL) using a browser on the mobile device 112.

The mobile device 112 is not limited to a mobile phone, and can include tablets, wearable devices, personal digital assistants (PDAs), laptop computers, “smart” watches, “smart” glasses, and any other device capable of receiving input from the customer 106, and which is capable of being connected to the network 116.

The software application 114 includes an interface that allows the customer 106 to enter the identifier. The identifier is then transmitted from the mobile device 112 via a network 116 to the management site 118. The identifier is received by the transceiver 124, and routed to the processing unit 120. The processing unit 120 performs a decryption and/or look-up operation in the database 122, and retrieves an unlock code for the over-lock 110 that is associated with the identifier. The unlock code is then transmitted by the transceiver 124 to the mobile device 112 via the network 116. The unlock code is subsequently displayed to the customer 106 on the mobile device 112 via the software application 114. Upon receiving the displayed unlock code, the customer 106 can then unlock the over-lock 110, and re-gain access to the storage unit 104.

FIG. 2 is a flowchart illustrating the steps of encrypting an unlock code for a combination over-lock. In step 200, a unique identifier is generated for the over-lock 110. The identifier can be generated at the time of manufacturing by the over-lock manufacturer, and can be transmitted with the over-lock 110 at the time of purchase by the self-storage facility. In this embodiment, the identifier can be engraved or permanently affixed to the over-lock 110.

In another embodiment, the identifier is generated by the self-storage facility. In this embodiment, an algorithm on the processing unit 120 randomly generates the identifier, or it can be generated manually by the self-storage facility. In another embodiment, a third-party over-lock provider can generate the identifier, and can sell or lease the over-locks to a self-storage facility. The third-party over-lock provider can manage the computing hardware and software 119 for the self-storage facility, and/or can lease the computing hardware and software 119 to the self-storage facility.

In an embodiment, the identifier can be generated using an encryption technique that utilizes the unlock code as an input. In addition, another identifying input can be utilized for the encryption along with the unlock code, such as a self-storage facility identifier, federal tax identification number, or a randomly generated string of characters.

In an embodiment, the identifier can be a string of numeric characters, alphabet characters, special characters, or a combination of alphanumeric and/or characters. In addition, the identifier can include a portion identifying the self-storage manager 108, the self-storage facility 102, and/or the customer 106.

In an embodiment where the identifier is a barcode, matrix code, a QR code, or a similar scannable code, the identifier can be printed on the over-lock 110 at the time of manufacture, or alternatively, the identifier can be printed on label and affixed to the over-lock 110 or a tag attached to the over-lock 110 by either the manufacturer or the self-storage facility.

In another embodiment, the over-lock 110 or tag can have a digitally imprinted code and/or microchip, such as a RFID or Bluetooth low energy transmitter. The customer 106 can be provided with a physical key fob that can read the code sent from the microchip, and which can display the code to the user. The key fob can be implemented into a software application on the mobile device 112 as well. In this embodiment, the identifier is not readily visible, which adds a layer of security against the over-lock 110, and its corresponding unlock code, becoming known over a period of time due to re-use.

In step 202, the unlock code is generated for the combination over-lock 110. Again, the unlock code can be generated at the time of manufacturing by the over-lock manufacturer, and transmitted with the over-lock 110 at the time of purchase by the self-storage facility.

In another embodiment, the self-storage facility can generate the unlock code for the over-lock 110. The unlock code can be randomly generated by an algorithm on the processing unit 120, or generated manually by the self-storage manager 108.

In an embodiment, the identifier and/or unlock code can be time-limited, and can expire after a pre-determined amount of time or on a certain date. In this embodiment, the expired identifier and/or unlock code must be re-generated as per step 200 and 202 above.

In an embodiment, the unlock code can be generated using an encryption technique that utilizes the identifier as an input. In addition, another identifying input can be utilized for the encryption along with the identifier, such as a self-storage facility identifier, federal tax identification number, or a randomly generated string of characters.

In step 204, the processing unit 120 associates the identifier with the unlock code for the over-lock 110 using an encryption technique. The encryption technique can include at least one of a hash function, a key derivation function, a block cipher operation, and an obfuscation function. In addition, the encryption algorithm used by the processing unit 120 can include a Triple Data Encryption Standard (DES) algorithm, a RSA cryptosystem algorithm, a Blowfish cipher algorithm, a Twofish cipher algorithm, or an Advanced Encryption Standard (AES) algorithm.

In step 206, the encrypted identifier and unlock code pair is stored in the database 122. The database 122 can be stored locally at the management site 118, can be located on a remote cloud-based server, or at another facility remote from the management site 118.

In yet another embodiment, each storage unit 104 can include a scannable code, such as a barcode, located on a visible portion of its exterior. Each over-lock 110 can also include a barcode as its identifier, as described above. Upon applying the over-lock to a storage unit 104, the self-storage manager 108 can scan both barcodes. These barcodes are then transmitted to the processing unit 120, where the barcode pairs are associated with each other and stored in the database 120.

FIG. 3 is a flowchart illustrating the steps of decrypting an unlock code for a combination over-lock. In step 300, upon encountering an over-lock 110 on their storage unit 104, the customer 106 locates the identifier on the over-lock 110. The customer 106 can enter the identifier into a software application 114 on their mobile device 112, as described above. In an embodiment, the customer 106 can take a picture of the identifier and send it via text, SMS, MMS, email, or secure message through the software application. to the management site 118. In another embodiment, the customer 106 can initiate a live-stream or video chat of the identifier with the management site 118, using, for example, Apple FaceTime®, Skype®, Snapchat®, or the like. In another embodiment, the identifier can be entered through a website accessed via a URL using a browser on the mobile device 112.

In another embodiment, the customer 106 can scan a barcode, matrix code, a QR code, or a similar scannable code with a camera or optical pickup means on the mobile device 112. The scanned identifier is then transmitted to the management site 118.

In yet another embodiment, the customer 106 can place a telephone call to the remote management site 106 and/or the self-storage manager 108 and provide the identifier and/or their credentials verbally.

In an embodiment, prior to being able to access the software application 114, the customer 106 must enter credentials, such as a login and password, or other indicia that verifies the customer's identity. The credentials may also be supplied via biometric means, such as with fingerprint, iris, voice, face, and gesture recognition means incorporated into the mobile device 112 and/or software application 114. In another embodiment, the credential can include a one-time or limited use password provided by a secure token, such as a RSA SecurID®.

In another embodiment, the credentials may be transmitted along with the identifier. In this embodiment, the credentials can include customer's mobile device number, login, password, email address, phone number, account number, personal identification number (PIN), name, driver's license number, social security number, birthdate, storage unit number, and/or a unique account identification code previously provided to the customer 106 by the self-storage facility and/or any combination thereof.

In yet another embodiment, the customer 106 can designate authorized parties who can request the unlock code as well. For example, a customer's spouse, authorized agents, business associates, attorneys, and any other parties whom the customer 106 wishes to have access to the storage unit 104 can have their credentials associated with the storage unit. In this embodiment, the database record for the storage unit 104 and/or over-lock 110 includes a listing of all authorized parties and their respective credentials.

In step 302, the identifier, along with the credentials, if required, are transmitted to the management site 118 via the network 116. In an embodiment, the identifier is specifically transmitted to the computing hardware and software 119, which can be located at the management site 118, or alternatively, located at a remote facility or server communicatively coupled to the management site 118.

As described above, the management site 118 and/or processing unit 120 can be located remotely from the self-storage facility 102, and thus, the network 116 can include a WAN and utilize broadband, cellular, and/or satellite communication means. In another embodiment, the processing unit 120 can be located on-site at the self-storage facility 102. In this embodiment, in addition to the aforementioned communication means, the mobile device 112 can utilize a short-range communication protocol, such as Bluetooth®, infrared, ZigBee®, and/or optical wireless, to communicate with the computing hardware and software 119.

In step 304, the processing unit 120 receives the identifier. The processing unit 120 uses the identifier as an input to decrypt the unlock code. Various decryption techniques may be employed, and such techniques can include the use of private and public keys. In another embodiment, the decryption step involves performing a look-up operation in the database 120 to locate the over-lock record associated with the identifier. Once the relevant record is located, the processing unit 120 extracts the unlock code from the over-lock record. The look-up operation can be standalone, or in addition to the decryption techniques described herein.

In another embodiment, the unlock code and identifier can both be randomly generated, either using an algorithm on a computing device, or manually. The randomly generated unlock code and identifier can then be linked or associated with one another in a database, table, matrix, ledger, or the like. The linking/associating can be done using an algorithm on the computing device, or can be done manually.

In step 306, the unlock code is transmitted to the mobile device 114 via the network 116 using a transceiver 124 coupled to the processor 120. Upon receipt by the mobile device 112, the software application 114 displays the unlock code to the customer 106. In yet another embodiment, the unlock code can be transmitted to the mobile device 112 from the management site 118 via SMS, MMS, email, or video chat. In yet another embodiment, the self-storage facility can place a telephone call to the customer 106 and verbally provide the unlock code. In this embodiment, human personnel, such as the self-storage manager 108 at the management site 118, can place via an automated system or the telephone call.

The unlock interface 600 allows the customer 106 to enter an identifier for the over-lock 110 at input box 602. The unlock interface 600 can also display information 604 such as the customer name and facility name, and customer status 606. The customer status 606 can be either “current” (i.e., paid in full and in good standing), or “delinquent” (i.e., having a past due balance). In an embodiment, the customer status 606 can include be “pending”, indicating that a payment has been submitted, but not yet processed, such as in the case of wire transfers or digital currency payments which typically require a delay in settlement.

In an embodiment, the unlock code 606 is displayed after the customer 106 transmits the identifier by selecting the “SUBMIT” button 610, and after the processing unit 120 successfully decrypts the unlock code.

In another embodiment, the interface 600 does not include the unlock code 606, and the unlock code is transmitted to the customer 106 via a text, SMS, MMS, email, video chat, secure message via the software application, or telephone call.

FIG. 6B is an illustration of an over-lock release interface for a software application according to an embodiment of the invention. In the event that the customer 106 has not made payment on a delinquent past due balance, and still attempts to retrieve the unlock code, the customer status 606 will be listed as “Delinquent”. In addition, the “SUBMIT” button 610 will be greyed our or inactive, so that the customer 106 cannot submit the identifier. In another embodiment, the customer 106 may not even reach the unlock interface 600, and rather, is directed toward a billing webpage upon launching the software application 114, where they can make a payment to rectify their delinquent account (not shown).

FIG. 7 is a flow chat illustrating the steps of enabling and disabling an over-lock according to the embodiment of the invention. In step 700, the management site 118 determines if a customer account is delinquent. If the account is current and there is no outstanding past due balance, the process terminates at step 702 and no over-lock 110 is required. The process continues back to step 700 where the customer account is continually monitored for delinquency by the management site 118.

If the customer account is delinquent, the process continues to step 704, where an over-lock 110 is placed on the storage unit 104. The over-lock 110, in a preferred embodiment, is manually placed over the primary lock or latch, thereby preventing movement of the door hasp, even if the primary lock is removed.

In another embodiment, the customer 106 can have multiple storage units on their account. If the customer 106 is delinquent on all or part of their account, all of the storage units on the customer's account can be over-locked. In another embodiment, only select storage units or a single storage unit can be over-locked, based on the amount or extent of delinquency on the account.

In step 706, the processing unit 120 determines if the customer account is still delinquent. If the account is still delinquent, the processing unit 120 disables the over-lock release function. In this scenario, the processing unit 120 prevents the over-lock release interface shown in FIG. 6B from returning an unlock code. In another embodiment, if the customer 106 attempts to request an unlock code via text message, email, video chat, or telephone call while having a delinquent past due account status, the customer 106 will be informed by the self-storage facility that their account is delinquent, and they cannot retrieve the unlock code.

If the customer's account is no longer delinquent in step 706, then the process continues to step 710, where the over-lock release is enabled by the processing unit 120, and the customer 106 can retrieve the unlock code in step 712. The process continues back to step 700 where the customer account is continually monitored either by the self-storage facility.

FIG. 8 is a flowchart illustrating the steps taken by a customer to retrieve an unlock code using the software application according to an embodiment of the invention. In step 800, the customer 106 discovers that their storage unit 104 has been over-locked.

In step 802, the customer 106 follows instructions on a notice from the self-storage facility to access the software application 114 in order to retrieve an unlock code for the over-lock 110. In an embodiment, a notice, such as a hangtag, placard, sign, or other indica is placed on the over-lock 110, adjacent to the over-lock 110, and/or on a door or frame of the storage unit. The notice can include instructions on how to access the software application 114. As discussed earlier, the software application 114 can be downloaded by the customer 106 from, for example, a website operated by the self-storage manager 108, the Apple iTunes App Store®, the Android App Store®, and the like, or the software application 114 can be a website accessed via a URL using a browser on the mobile device 112.

In an embodiment, the notice can instruct the user to launch the software application 114 on their mobile device 112, can instruct the user to visit a URL using a browser on their mobile device 112, and/or can include a scannable code which automatically launches the software application 114 or a URL on the mobile device 112. In another embodiment, the notice can instruct the user to place a telephone call or send a message, such as a SMS, MMS, or email, to the self-storage facility.

In another embodiment, the notice can be sent directly to the customer 106, such as via text, SMS, MMS, email, or secure message through the software application. The notice can include a URL or other mechanism to launch the software application 114 on the mobile device 112. In addition, the notice can be mailed via physical mail to the customer's address on file.

In yet another embodiment, the notice can be a telephone call from the management site 118, instructing the customer 106 to access the software application 114.

In step 804, the customer 106 is prompted to enter their credentials, such as a login and password, or other indicia that verifies the customer's identity. The credentials may also be supplied via biometric means, such as with fingerprint, iris, voice, face, and gesture recognition means incorporated into the mobile device 112 and/or software application 114. In another embodiment, the credential can include a one-time or limited use password provided by a secure token, such as a RSA SecurID®.

In step 806, the management site 118 determines if the credentials are valid. If not, the process returns to step 804, and the customer 106 is prompted to re-enter their credentials. If the credentials are deemed valid, then in step 808, the management site 118 determines if the customer's account is indeed delinquent. If the customer 106 no longer has a past due balance, then the customer 106 is prompted to enter the identifier from the over-lock 110 in step 810. This scenario may occur, for example, if a customer 106 makes a payment to rectify a past due balance from a remote location, such as their home or work, and then subsequently arrives at the self-storage facility to discover a previously placed over-lock 110.

If the customer 106 still has a past due balance, then the customer 106 is prompted to pay their past due balance in step 812. In an embodiment, the customer 106 can make payments to the self-storage facility via a credit card, debit card, automated clearing house (ACH) transfer, and wire transfer. The software application 114 may allow the user to store a payment method on file, such as a stored credit card, or a linked bank account.

In addition, the self-storage facility can accept payment via third-party payment processing systems, such as PayPal®, Stripe®, Apple Pay®, Android Pay®, Square®, Amazon Payments®, Viewpost®, and other similar platforms. Such payment processing systems can be integrated within the software application 114.

In yet another embodiment, the self-storage facility can accept payment via cryptographic and digital currencies, such as, but not limited to Bitcoin, Ethereum, Litecoin, and Nano.

In another embodiment, the customer 106 can visit the manager self-storage and/or the remote management site 118 and pay the past due balance in-person.

The process then returns to step 808, where the management site 118 determines if the customer 106 still has a past due balance on their account. If there is no past due balance, then the customer 106 is prompted to enter the identifier from the over-lock 110 in step 810. If the customer 106 still has a past due balance, then the process returns to step 812 where the customer 106 is prompted to pay their past due balance.

In step 814, the management site 118 transmits the unlock code to the customer 106, who can then remove the over-lock 110 from their storage unit 104.

FIG. 9 is a flowchart illustrating the steps taken by a customer to retrieve an unlock code via a telephone call according to an embodiment of the invention. In step 900, the customer 106 discovers that their storage unit 104 has been over-locked.

In step 902, the customer 106 follows instructions on a notice from the self-storage facility to call the management site 118 in order to retrieve an unlock code for the over-lock 110. In an embodiment, the management site 118 can include a self-storage manager 108, call center, representative, or third-party answering service. In another embodiment, the customer 106 can send a message to the management site 118, such as via text, SMS, MMS, email, or secure message through the software application in order to schedule a call from the management site 118.

In step 904, the management site 118 requests the customer 106 to provide credentials, as described above.

In step 906, the management site 118 determines if the credentials are valid. If not, the process returns to step 904 and the management site 118 requests the customer 106 to provide their credentials again. If the credentials are deemed valid, then in step 908, the management site 118 determines if the customer's account is indeed delinquent. If the customer 106 no longer has a past due balance, then the customer 106 is prompted to enter the identifier from the over-lock 110 in step 910. The customer 106 can verbally provide the identifier, enter the identifier via their alpha-numeric keypad on their mobile device 112, or scan the identifier and transmit it to the management site 118 using their mobile device 112.

If the customer 106 still has a past due balance, then the customer 106 is prompted to pay their past due balance in step 912.

The process then returns to step 908, where the management site 118 determines if the customer 106 still has a past due balance on their account. If there is no past due balance, then the customer 106 is prompted to provide the identifier from the over-lock 110 in step 910. If the customer 106 still has a past due balance, then the process returns to step 912 where the customer 106 is prompted to pay their past due balance.

In step 914, the management site 118 provides the unlock code to the customer 106, who can then remove the over-lock 110 from their storage unit 104.

In an embodiment, the over-lock 110 can include an emergency mode, where emergency personnel, such as first responders, police, firefighters, and emergency medical service providers and request an unlock code. In this embodiment, the emergency personnel can transmit an emergency credential along with the identifier. Upon receipt of the emergency credential by the management site 118, the processing unit 120 foregoes credential verification and proceeds with decrypting the unlock code.

In yet another embodiment, the over-lock 110 is an electronic lock that accepts a combination input via digital keys or a touchscreen. The customer 106 can be provided with a secure token that provides a one-time or limited use password, such as the RSA SecurID®. In the event of a delinquent past due balance, the management site 118 can remotely disable the secure token until the customer 106 makes a payment of the past due balance.

In another embodiment, the entire process of retrieving an unlock code by the customer 106 can be automated. For example, the management site 118 can include an automated attendant that verifies the identity of the customer 106 via the means described above, receives the identifier from the customer 106, and provides the unlock code to the customer 106. The process can also occur in an automated fashion without human intervention from the self-storage facility or management site 118 via the kiosk 500.

FIG. 10 is a flowchart illustrating the steps taken by a customer to retrieve an unlock code using the software application and a customer account identifier according to an embodiment of the invention.

In step 1000, the customer 106 discovers that their storage unit 104 has been over-locked.

In step 1002, the customer 106 follows instructions on a notice from the self-storage facility to access the software application 114 and/or website in order to retrieve an unlock code for the over-lock 110 as described herein.

In step 1004, the customer 106 is prompted to enter their credentials, such as the customer's mobile device number, email address, login, password, phone number, account number, personal identification number (PIN), name, driver's license number, social security number, birthdate, and/or a unique account identification code. The over-lock identifier and/or unlock code is previously associated with the storage unit and/or customer.

The unlock code and/or over-lock identifier can be previously associated with the storage unit and/or the customer. This association can be in the form of a mapping table in the database 122. In one embodiment, at the time of placing the over-lock on the storage unit 104, the unlock code for the over-lock is mapped to the storage unit 104 and/or customer record in the database 122. During a subsequent lookup, the storage unit 104 or customer information is required by the processing unit 120 to retrieve the unlock code. In this embodiment, the unlock code and storage unit 104 and/or customer information may or may not be encrypted.

In another embodiment, the over-lock identifier is generated using an encryption technique using the unlock code. The over-lock identifier can then be associated with an over-lock, and/or can be associated with the storage unit 104 and/or customer. In the event that the over-lock identifier is associated with the storage unit 104 and/or customer, then the storage unit 104 and/or customer are also associated with the corresponding over-lock in the database 122. During a subsequent lookup, the over-lock identifier is required by the processing unit 120 in order to decrypt the unlock code.

In step 1006, the management site 118 determines if the credentials are valid. If not, the process returns to step 1004, and the customer 106 is prompted to re-enter their credentials. If the credentials are deemed valid, then in step 1008, the customer is prompted to enter an account identifier. In this embodiment, the management site 118 receives the customer account identifier, and the management site 118 does not necessarily receive a serial number or unique identifier of the over-lock itself. The account identifier can include, but is not limited to, a storage unit/unit number, an account number, and any other identifier that associated the customer with a specific account or storage unit or units. The management site 118 performs a look-up function using the account identifier. The look-up function correlates the account identifier with the storage unit 104, the over-lock identifier and/or the unlock code, as well as a customer account.

In step 1010, based on the look-up, the management site 118 determines if the customer account is delinquent. If the customer 106 still has a past due balance, then the customer 106 is prompted to pay their past due balance in step 1012 as described herein. If there is no past due balance, then the management site 118 transmits the unlock code to the customer 106 in step 1014, who can then remove the over-lock 110 from their storage unit 104.

If the customer 106 still has a past due balance in step 1010, then the customer 106 is prompted to pay their past due balance in step 1012 by any of the means described herein.

FIG. 11A is an illustration of an over-lock release interface that receives an account identifier for a software application according to an embodiment of the invention. The unlock interface 600 can be displayed on the mobile device 112 once the customer 106 activates the software application 114. The interface 600 is displayed after the customer 106 has entered their credentials and has been verified by the management site 118. The unlock interface 600 allows the customer 106 to enter a customer account identifier, such as, for example, their storage unit number, at input box 602. The unlock interface 600 can also display information 604 such as the customer name and facility name after receiving the customer account identifier, and customer status 606. The customer status 606 can be either “current” or “active” (i.e., paid in full and in good standing), or “delinquent” (i.e., having a past due balance). In an embodiment, the customer status 606 can include be “pending”, indicating that a payment has been submitted, but not yet processed, such as in the case of wire transfers or digital currency payments which typically require a delay in settlement.

In an embodiment, the unlock code 608 is displayed after the customer 106 transmits the identifier by selecting the “SUBMIT” button 610, and after the processing unit 120 successfully decrypts the unlock code. If an over-lock identifier was previously associated with the storage unit, the processing unit 120 can perform a lookup of the over-lock identifier and perform the decryption step, as described previously herein. In the event that the unlock code was previously associated with the storage unit, then the processing unit 120 performs a lookup of the storage unit to retrieve the associated unlock code.

FIG. 11B is an illustration of an over-lock release interface that receives an account identifier for a software application according to an embodiment of the invention. In the event that the customer 106 has not made payment on a delinquent past due balance, and still attempts to retrieve the unlock code, the customer status 606 will be listed as “Delinquent”. In addition, the “SUBMIT” button 610 will be greyed our or inactive, so that the customer 106 cannot submit the identifier. In another embodiment, the customer 106 may not even reach the unlock interface 600, and rather, is directed toward a billing webpage upon launching the software application 114, where they can make a payment to rectify their delinquent account (not shown).

FIG. 12 is a flowchart illustrating the steps taken by a customer to retrieve an unlock code via a telephone call using only an account identifier according to an embodiment of the invention. In step 1200, the customer 106 discovers that their storage unit 104 has been over-locked.

In step 1202, the customer 106 follows instructions on a notice from the self-storage facility to call the management site 118 in order to retrieve an unlock code for the over-lock 110. In an embodiment, the management site 118 can include a self-storage manager 108, call center, representative, or third-party answering service. In another embodiment, the customer 106 can send a message to the management site 118, such as via text, SMS, MMS, email, or secure message through the software application in order to schedule a call from the management site 118.

In step 1204, the management site 118 requests the customer 106 to provide their credentials, as described herein.

In step 1206, the management site 118 determines if the credentials are valid. If not, the process returns to step 1204, and the customer 106 is prompted to re-provide their credentials. If the credentials are deemed valid, then in step 1208, the customer is prompted to enter an account identifier. In this embodiment, the management site 118 receives the customer account identifier, and the management site 118 does not necessarily receive a serial number or unique identifier of the over-lock itself. The account identifier can include, but is not limited to, a storage unit/unit number, an account number, and any other identifier that associated the customer with a specific account or storage unit or units. The management site 118 performs a look-up function using the account identifier. The look-up function correlates the account identifier with the storage unit 104, the over-lock identifier and/or the unlock code, as well as a customer account.

If there is no past due balance, then the management site 118 transmits the unlock code to the customer 106 in step 1214, who can then remove the over-lock 110 from their storage unit 104.

If the customer 106 still has a past due balance, then the customer 106 is prompted to pay their past due balance in step 1212. The process then returns to step 1210, where the management site 118 determines if the customer 106 still has a past due balance on their account.

FIG. 13 is a flowchart illustrating the steps taken to apply an over-lock to a vacant storage unit. In step 1300, the self-storage facility applies an over-lock to a vacant storage unit. In step 1302, the over-lock identifier is assigned, mapped, associated with, or linked to the specific vacant storage unit in a database coupled to a lock management system operated by the management site. In an embodiment, the over-lock identifier and/or the unlock code for the over-lock are mapped to the specific vacant storage unit in the database.

As discussed above, the management site can be separate from the self-storage facility, and can be owned and/or operated by an entity different from the self-storage facility. In an embodiment, the self-storage facility is a customer of the management site, and purchases a subscription, license, or the like to the lock management system, from the management site.

In step 1304, the unlock code is transmitted from the lock management system to a third-party property management system via an application programming interface (API). In an embodiment, the third-party property management system is owned and/or operated by an entity different from the management site and/or the self-storage facility. The third-party property management system can be, but is not limited to, software offered by, for example, storEDGE®, SiteLink®, Storage Commander®, QuikStor®, 6Storage®, Tredds Self Storage®, Easy Storage Solutions®, Convoyant ResNexus®, and the like.

The API allows the lock management system to communicate with the third-party property management system, and allows either unidirectional or bidirectional transmission of data between the two systems.

In an embodiment, the lock management system is a completely separate and distinct software program from the third-party property management system. The lock management system and the third-party property management system can be located on different servers, and only coupled via the API, and not by any direct, physical network communication links. Furthermore, the lock management system can integrate with various different third-party property management systems via multiple APIs, such that a single lock management system can communicate with multiple different, disparate third-party property management systems.

FIG. 14 is a flowchart illustrating the steps taken to retrieve an unlock code from a third-party property management system for an over-lock secured to a vacant storage unit. In step 1400, a customer arrives at a vacant storage unit that is secured with an over-lock. In an embodiment, the storage unit or over-lock includes a notice that has instructions for the customer on how to request an unlock code for the over-lock.

The notice can instruct the user to launch a software application on their mobile device, and/or can instruct the user to visit a portal for the lock management system using, for example, a URL on a browser on their mobile or computing device, and/or can include a scannable code which automatically launches the software application or a URL on their mobile device. In another embodiment, the notice can instruct the user to place a telephone call or send a message, such as a SMS, MMS, or email, to the self-storage facility or management site.

In another embodiment, the notice can be sent directly to the customer via text, SMS, MMS, email, or secure message through the software application, such that the customer does not physically have to visit the vacant storage unit to view the notice. The notice can include a URL or other mechanism to launch the software application on their mobile device. In addition, the notice can be mailed via physical mail to the customer's address on file.

In step 1402, the customer accesses the lock management system portal, which is described in more detail above and depicted in FIGS. 11A and 11B. Further in step 1402, the customer is prompted to enter their credentials, such as the customer's mobile device number, email address, login, password, phone number, account number, personal identification number (PIN), name, driver's license number, social security number, birthdate, and/or a unique account identification code.

In step 1404, the lock management system transmits the customer credential(s) and a storage unit identifier and/or over-lock identifier to the third-party property management system via the API. This step does not require human or manual intervention or action; the lock management system automatically and seamlessly transmits the customer credential(s) after receiving them from the customer via the portal.

In step 1406, the third-party property management system determines if the customer is truly a verified renter of that specific storage unit. If not, the customer request for the unlock code is denied in step 1408.

If, however the customer is a verified renter of that specific storage unit, the process continues to step 1410 where the third-party property management system determines if the customer's account is delinquent. If the customer's account is not current and there is an outstanding past due balance, the process continues to step 1412 where the customer is prompted to make a payment to rectify their past due balance, as discussed in more detail above. The process can then return to step 1410 where the customer's account status is once again verified.

If the customer's account is current and there is no outstanding past due balance, then the process continues to step 1414 where the third-party property management system transmits the unlock code to the customer. In an embodiment, the unlock code can be transmitted to the customer via text, SMS, MMS, email, secure message through the software application, displayed on the customer's browser, or via an automated telephone call. Again, this step does not require human or manual intervention or action on the part of the self-storage facility, management site, or third-party property management system provider.

FIG. 15 is a flowchart illustrating the steps taken to retrieve an unlock code from a lock management system for an over-lock secured to a vacant storage unit. In this embodiment, the process is similar to the steps described above for FIG. 14. However, in step 1500, the third-party property management system can transmit the customer's contact information, such as their mobile phone number, email address, and the like, to the lock management system via the API. In step 1502, the lock management system transmits the unlock code to the customer. In an embodiment, the unlock code can be transmitted to the customer via text, SMS, MIMS, email, secure message through the software application, displayed on the customer's browser, or via an automated telephone call. Again, this step does not require human or manual intervention or action on the part of the self-storage facility, management site, or third-party property management system provider.

In an alternative embodiment, in lieu of either steps 1414 of FIG. 14 or 1502 of FIG. 15, the unlock code can be transmitted to the self-storage facility manager or operator, or to a human operator at the management site, who can be then provide the unlock code to the customer via a phone call or in person, or via text, SMS, MMS, email, or secure message through the software application.
